Advantages Of Graphite Coatings
Graphite is one of the popular metals in the world. Graphite is widely used in developed refractories and coating gold treatment industries. It has got many uses thus making many industries to use in producing materials that help in every day’s life. After processing graphite in-depth, flake graphite is used to produce graphite emulsion used as a lubricant, release agent, drawing agent, conductive coatings. It can also be used to produce expanded graphite for raw materials of pliable graphite materials. The main reason for using graphite widely is that its products have several advantages. The numerous benefits of graphite coating include the following.
Good thermal conductivity. Graphite is one of the metals that has good thermal conductivity. Its thermal conductivity can be compared with aluminum, copper, and iron, but comparing thermal conductivity of graphite with ordinary metals, it has a quite high thermal conductivity than them. when graphite powder is compressed under high temperatures, it has ultra-high temperatures making it differ from the general metal materials. The thermal conductivity of general metals tends to increase with an increase in temperatures. Graphite powder is seen to be isothermal at a very high temperature.
High-temperature resistance. Graphite powder is one of the known metals having high-temperature resistance in the world. When graphite is compressed to a high temperature above 2000, it will be in the molten state and will not be melted. Graphite has a low loss rate when compressed to ultra-high temperatures. The strength of general metals decreases gradually when they are at high temperatures. The strength of graphite thus increases doubly when compressed to high temperatures making it different from the general metals.
Graphite has a good lubricity character. Graphite has less friction coefficient. Its lubrication coefficient thus varies with the scale size it has. The good lubricant performance is achieved when there is a larger scale thus a smaller friction coefficient. Graphite also has no pungent smell at a higher temperature compared to molybdenum.
Excellent thermal shock resistance. Graphite does have good thermal shock resistance. When the temperature suddenly changes, there will be a small thermal expansion coefficient felt. Graphite products thus have good thermal stability thus do not produce cracks when they are compressed to high temperatures.
Good chemical stability. Graphite products have good chemical stability at room temperatures. They can resist corrosion of acids, alkalis thus organic solvents. They are easy to oxidize at higher temperatures oxidation medium.
Saves time. When you have the graphite materials that should be connected, it will reduce your time as the number of electrodes to be connected will be reduced, making you save much time upon connecting the electrodes. Also, the working conditions of your furnace stuff will be highly improved reducing the time that could have been spent doing that task. The crane time thus will be reduced as well.
Improved conductivity of the electrodes. Upon doing the connections of your home system, there will be improved conductivity in the electrodes by using high conductive graphite. There will be a uniform distribution of current flow in the system as graphite has delocalized electrons in a molten state.
